My stress-test agrees and finds no additional concern more central. The paper is a review, not a primary study, so its contribution is a map of the literature; the conditional verdict is appropriate because the map is useful but its headline conclusion outruns the evidence. The proposed concrete test would settle whether the specific numbers that carry the conclusion are trustworthy, which is the needed condition for the central claim. I do not see a reason to move the verdict to reject or accept: the paper's flaws are correctable, and the conditional framing already communicates the required caution.","tokens_in":19837,"tokens_out":1477,"duration_ms":19300,"concrete_test":"Select the two largest claimed quantum advantages in Table III: the heart/thyroid results from [94] and the MNIST results from [101]. Retrieve the original papers, reconstruct their exact train/test splits and preprocessing, and retrain three well-tuned classical baselines (e.g., XGBoost, a standard CNN, and a regularized logistic regression) on the same data. If any classical baseline matches or exceeds the reported accuracy within one standard deviation, the Table III evidence no longer supports a quantum-specific benefit, and the conclusion should be weakened to reflect that the reviewed studies do not yet establish quantum advantage.","verdict_should_be":"UNCHANGED","load_bearing_attack":"The central claim in Section V is that current QNN developments have 'enormous potential to revolutionize' healthcare 5.0. The only direct evidence offered is the set of cited studies summarized in Section III and Table III. Those entries are reported at face value: e.g., [94] is listed as achieving 99.23% (heart) and 99.97% (thyroid) with no indication of whether these are test-set accuracies, what cross-validation was used, how class imbalance was handled, or what classical model was used as a baseline. The entry for [101] reports 99% on MNIST for a 'Quantum Relu activation function' even though the surrounding text describes QReLU and m-QReLU as quantum-inspired activation functions used inside ordinary CNNs, not necessarily as quantum neural networks. This conflation matters: if the reported gains come from classical network capacity, regularization, or dataset quirks rather than from quantum resources, then the paper's narrative that QNNs are ready to contribute to healthcare collapses. Because the review performs no independent verification and applies no selection criteria, the load-bearing assumption is that every number in Table III is both accurate and attributable to the quantum component. That assumption is not secure.","agreement_with_reader":"agree"},"referee_report":{"model":"deepseek-v4-flash","summary":"This manuscript is a narrative review of quantum neural networks (QNNs) applied to the healthcare 5.0 context. It provides introductory background on quantum computing and QNN architectures, a year-based and taxonomy-oriented classification of recent applications, a comparison table of specific QNN-based systems, and a list of challenges and future directions. The central claim, stated in the conclusion, is that current QNN developments have \"enormous potential to revolutionize\" areas of healthcare 5.0 such as predictive modeling, drug discovery, medical image analysis, and operations management. The paper contributes no new experiments or derivations; its evidence consists of summaries of previously published studies, primarily organized in Tables I–III.","tokens_in":20051,"tokens_out":3329,"duration_ms":38529,"significance":"If the reported literature were critically synthesized, this review could serve as a useful entry point for researchers and practitioners interested in QNN applications in healthcare. The manuscript does a service by compiling a large number of recent works, organizing them by application area and technology, and explicitly listing open challenges and future directions. However, its significance is currently limited by the uncritical acceptance of secondary accuracy figures and by the absence of a systematic methodology or a critical assessment of whether reported gains are attributable to quantum resources. The conclusion that QNNs have \"enormous potential to revolutionize\" healthcare is therefore stronger than the evidence presented in the manuscript supports. The paper is best seen as a broad survey that needs tempering and methodological scaffolding before its central claim can be assessed.","major_comments":[{"comment":"The paper calls its analysis a \"comprehensive\" review and a \"detailed comparison,\" but it does not state a search strategy, inclusion/exclusion criteria, or any quality assessment for the surveyed works. Without such methodology, the selection of studies in Tables I–III may not be representative, and the reader cannot distinguish systematic coverage from an arbitrary collection. Adding a short methodology paragraph or at least an explicit statement of selection criteria would substantially strengthen the review's evidentiary basis.","section":"§III and Tables I–III"}],"minor_comments":[{"comment":"In the variational principle steps, the expectation value is written as \"⟨ψ(vec(θ)H|ψ(vec(θ)⟩\", which appears to be missing a vertical bar and a closing angle bracket.

Its main weakness is not the absence of new experiments, which is expected for a review, but the lack of critical scrutiny of the very numbers that support its central claim.

The paper may also be a better fit for a survey-oriented venue than for a primary research journal, although that is a scope decision for the editor."},"author_rebuttal":null,"desk_editor":{"model":"deepseek-v4-flash","letter":"Quick note on arXiv:2412.06818. This is a survey, not a research contribution. No new experiments or derivations. What it does usefully: pulls together a large number of recent papers on quantum and quantum-inspired neural networks in healthcare, organizes them around Healthcare 5.0 themes, and gives comparison tables. That bibliographic map has real value for someone entering the field.\n\nThe soft spots are mostly at the level of claims and editorial care. Table III reports accuracies like 99.97%, 99.23%, and 99% straight from the cited papers, with no baseline definitions, no error bars, no dataset standardization, and no discussion of what the quantum component actually contributes. The text even lists a 'Quantum Relu activation function' entry as a QNN technique when the source paper describes quantum-inspired activations used inside ordinary CNNs. That's a category error, and it matters because the paper's conclusion that QNNs have 'enormous potential to revolutionize' healthcare rests on those secondary numbers. If the reported gains are mostly classical capacity or dataset quirks, the conclusion is hollow. The review should either re-report cautiously or drop the strong claim.\n\nAlso small but real: Eq (1) has a typo in |α, Eq (15) has a garbled matrix, and the introduction attributes quadratic speedups to Shor's algorithm, which is off. Not fatal, but it signals a lack of careful proofing.\n\nOn the positive side, the paper is honest about limitations in the future directions section, and it does not invent a framework or claim a derivation. It's a conventional narrative review with useful tables.\n\nWho should use it? A newcomer wanting a rapid, skeleton map of the literature could read it, then go to the primary sources. It should not be used as evidence that QNNs work in healthcare. The reader's conditional verdict is right. I'd send it to peer review only with major revisions: systematic search protocol, re-analysis of the accuracy claims, separation of true quantum from quantum-inspired, and corrections. If it's already a preprint, treat it as a pointer list, and don't cite the accuracy table.","headline":"A useful but non-systematic literature map whose empirical claims need heavy qualification; fine as a pointer, not as evidence.","tokens_in":20532,"tokens_out":2308,"would_cite":false,"duration_ms":26059,"reading_group":"maybe","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"This paper argues that quantum neural networks could reshape Healthcare 5.0, with recent case studies reporting high accuracies in diagnosis, drug discovery, and medical imaging.","keywords":["quantum neural networks","healthcare 5.0","quantum machine learning","medical image analysis","drug discovery","hybrid quantum-classical systems","quantum blockchain","smart healthcare"],"falsifier":"Re-run the heart-disease and thyroid predictors from the quantum-inspired heuristic study [94] with a well-tuned classical neural network on the same standardized data and matching training budget; if the classical model matches or exceeds 99.23% and 99.97% accuracy, the paper's implicit claim that the quantum components drive the reported performance would be undercut.","tokens_in":19620,"feed_emoji":"🩺","tokens_out":6951,"duration_ms":69244,"temperature":0.7,"pith_summary":"This paper is a review that argues quantum neural networks (QNNs) are poised to play a major role in Healthcare 5.0, the patient-centered use of AI, the Internet of Things, robotics, and blockchain in medicine.
